Pass external delegate to a class constructor.

[Marty]

Hi,

I would like to have my class to execute eventually an outside function.

I was thinking to pass to my class constructor a delegate object that
would be later used in my class to be triggered.

Does a delegate is the correct object to use to do that?

Thanks!
Marty

Re: Pass external delegate to a class constructor.

Marty,

The delegate will provide you with a pointer to another method, either
external or internal to your class depending on how your access is
setup. They are especially useful for events, which is what it sounds
like you want.

Hi Brett,

Yes events will solve the thing, thank you :)

Yes. Delegates are like function pointers in C and are designed for just
that.

Re: Pass external delegate to a class constructor.

Hi cody,

I finally used delegate and events, but reading your comment, I'm
thinking that I could have done that without the events.

I saw example over the internet, but every time, the delegate
declaration was in a targetted class.

I would like the outside delegate callback function to be set within the
class constructor. Do you know how to do that?

something like:

class1:
myTriggerFuncti on() //This one to be used from class2.

class2:
constructor: record class1.myTrigge rFunction() delegate address.
anotherFunction : trig recorded myTriggerFuncti on() delegate address.

Hope this give you an idea of want I want to do.
Thanks a lot!
Marty

Re: Pass external delegate to a class constructor.

something like that?

public delegate void MyDelegate(); // can be declared outside classes

public MyClass
{
MyDelegate d;

public MyClass(MyDeleg ate d)
{
this.d=d;
}

void Trigger()
{
if (d!=null)
d();
}
}
